CentOS 5 :: Cluster Suite And Fence For VMWare ESXi 4.0
Oct 22, 2009
This is my first post, and i have a question with the fence software for VMWare ESXi. The fence_vmware agent only works with ESX, and redhat (in you GIT repository) has submited a new agent called fence_vmware_ng that claims to work with ESXi. But the problem is that they do not specify the version that works with that. Anybody has test the fence_vmware_ng agent for VMWare ESXi 4.0 ?, i follow the instructions here: [URL]...and i can install the software, the API from VMWARE site, etc, but in the moment when i run the agent nothing happen, The agent connects to server, i see in logs, but the off-reboot-on operations not works. Only works status operations, that return the state of a virtual machine. I have CentOS 5.3 (fully today updated) with RHCS.

I have just installed a two server cluster with ricci luci and conga on centos 5.6 32bit , both servers are vmware guests and have a shared storage disk connected to them both
with a GFS2 file system on them + fencing agents configured to work with VMware Vcenter.
(this is supported by vmware and works great on 4 other centos clusters i have been runing for 4 monthes with no CLVMD).
In this setup i used for the first time CLVMD as recommnded by RedHat so i could have the flexablitly of LVM under the GFS2 file system but , i have been getting some Strange problem with it , some times after a developer has done some IO heavy task like unziping a file or a simple TAR the load goes to 10 - 15 and no task can be killed , trying to reboot the server hangs.
After hard shutting the server every thing works ok until the next time some one does the same IO work as before.

I have made a cluster between two server.In luci I can see that my cluster is green and the two nodes to.I have make an IP resource and associate it to a service : green : I can relocate the service from a node to the other one and the IP appears in the list of IP addresses The problem is that I have made the same in order to configure tomcat and postgresql and it does not work...I put my configuration only for ip and tomcat:
My host configuration:
127.0.0.1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
10.0.0.1 server1.domain.com server1
10.0.0.2 server2.domain.com server2

I am trying to build GFS2 cluster with 2 or 3 Fedora 14 nodes, but I've encountered some problems from the start. First luci does not work at all in Fedora 14. There is no luci_admin and even if I manage to start luci service, I get a blank white screen when I try to open it from the browser. I've googled a bit and found that I'd might be able to setup GFS if I manage to build cluster.conf manually and start the cluster suite, but I cannot find documentation on how to create cluster.conf anywhere. If anyone knows how to setup GFS2 without a cluster suite or how to configure cluster.conf.

I can't install centos 5 on vmware esxi 4 server.I use the netinstall cdrom and I get the splash screen with the kernel menu.After this, I can choose a language but then I get this error: "The CentOS CD was not found in any of your CDROM drives. Please insert the CentOS CD and press OK to retry."
I have tried it with the image on the datastore, a unc-path and as physical cdrom.I have tested all modes in the vmware cdrom settings (passthrogh IDE or Emulate IDE) - nothing helps.
Console 3 shows me:
loaded mptbase from /modules/modules.cgz
loaded mptscsihfrom /modules/modules.cgz[code]...........

I am working in a project that needs to set up an Apache Web Cluster. The cluster needs to be High-availability (HA) cluster and Load-balancing cluster. Someone mentioned the use of Red Hat Cluster Suite, but, honestly, I can't figure out how it works, I haven't been able to configure it correctly. The project currently have two nodes, but we need to support at least three nodes in the cluster.

Installed CentOS 5.5 on VMware ESXi server running vsphere 4.1. Installed fine and picked the E1000 network adapter. But can't get the adapter to become active and pick up an IP address. Has anyone done this before? I can't get it to work. When i was testing CentOS out i used VirtualBox and worked fine using bridged networking but just can't seem to get this network card working.I've put some pictures of the config i've got.http:[url]....

I am using the Redhat Cluster Suite (luci and ricci) on my centos 5.4. i have 2 nodes in a cluster.I had clustered an apache server.The service is up end running and i can stop,start and switch on all two node.The problem is when i try to simulate a fault for one node.For example:The apache resource stay on the first cluster node.If i power off the first cluster node (not halt or init 0 but take off the eletric power off), the second cluster node not take the resource.With the clustat command, the service still running on the first node.But the service is down. The first node is dead.Only one the first node is join again the cluster the resource goes up on the second node.

run VMWare ESXi and have installed Ubuntu 10.10 in a virtual machine.People say you press CRTL+ALT+F1 to exit back to command line from the gnome login screen but this never works for me.If I do something like "sudo service gdm stop" it just delivers me to the desktop background almost like the machine has hung, no menus toolbars, mouse or anything.Basically what I want to be able to do is start up the machine with command line, and go into gnome on occasion and exit back out to command line to save resources, this is because the machine will mainly serve as a web server. I followed the guide here [URL] which tells how to make ubuntu always start at CLI, which works nicely, but I need a way to be able to get back to CLI from inside gnome.

Can I install VMware ESXi on my Dell Inspiron laptop having core i3 processor which has got 4GB of RAM? I can allocate 100GB of hard disk space for that. This is just to practice and explore the features available. Can I install Vmware ESXi iso on KVM hypervisor like installing guest OS?

I have a freshly installed, updated Fedora 11 installation for which the VMWare Tools fails. It can't compile what it needs, either. It's running under ESXi 3.x.

My boss asked me to convert the company's web server (running on ubuntu 10.04 server LTS and using CMSME for the website),and the company's router directs the domain to that machine.The webserver is getting old (P3) and the server just freeze every morning and require a manual reboot most mornings.
He wants me to convert the ubuntu server to a virtual machine and host it on a ESXi server. For the past few week (im working part-time so not everyday), trying different ways to host the webserver.I tried using the VMware Converter 4.0 to the ESXi server (That didn't work)I tried using Acronis Echo workstation to create a image and trying to convert it using the VMware converter (The ESXi console says Error Operating System)

We are having some problems in running CentOS 5.3 in our ESXi 3.5 environment. The virtual machine is running perfectly under VMWare Player, but when I converted it to ESXi using VMWare vCenter Converter 4.0.0, the CentOS often goes into a panic right at the start of stops when setting up the hostname.

We've been having lots of problems with burning CD-Rs on our Dell PowerEdge and T300 servers. We've had the CD recorders replaced frequently, and that often fixes the problem, but then we'll start having problems again. Usually it is the CD refuses to write, or it gets written but can't be read. Often, if I re-run the burn with the same blank CD, it will be fine.
I'd like to test some CD-Rs and compare error rates so I can recommend what CD-R media we should be using. Currently we are using Memorex and Verbatim CD-Rs. Is there a good cd recording/testing suite for Linux that I could use to do this?

I'm having a very strange problem with red hat cluster. After testing it in the lab, I tried to install a new cluster and received the following error: cman not started: Cannot start, cluster name is too long or other CCS error /usr/sbin/cman_tool: aisexec daemon didn't start I've checked the internet for that error, but nothing. I decided to to take the example from cluster.conf man, which looks like that :
[Code]...
And still I get the same error. I can find my servers both from DNS (FQDN and short name) and they also appear in /etc/hosts.

What I did not realize was, that DLM uses the external Ethernet Interface even when talking to the local machine/node. So iptables was blocking my DLM daemon. With iptables down or the TCP port for DLM opened, cman starts, mount works.What I have here is a fibrechannel SAN which will be directly attached to several servers in the near future. Thise servers should be enabled access to a single filesystem on the SAN (shared).I heard that the right filesystem choice for this kind of setup would be GFS, because it has a Distributed Lock Manager and one FS journal for each node.
But I am having trouble setting up GFS. I have managed to create a GFS on a small testvolume (local HDD so far), but am unable to mount it. It seems that GFS/DLM needs a lot of cluster services to run, which I do not all understand / know how to correctly setup. Also: Will the lock_dlm stuff need Ethernet communications to handle file locks? And if so, will it fetch the node list from /etc/cluster/cluster.conf to determine who to talk to?

I created a cluster with two nodes and a machine for managers with luci, if a machine reboot the cluster function by transferring the resource (IP address), if forced to stop the machine (pull the plug) the cluster does not work.
